Treatment Options For Patients With High Anti
So what are you supposed to do if you have high anti-TPO antibody levels?
It turns out that there are several things you can do to lower these antibody levels.
The treatment is especially important because your physician may take the wait and see approach to treatment.
Basically many doctors may not even try to treat your antibody levels until they have caused glandular damage and thyroid hormone replacement is required.
Luckily there are several therapies that you can do to help reduce inflammation and autoimmunity.
Note: for best results, its wise to use a combination of these therapies and stack them together. If you take just 1-2 supplements, for instance, you will be limiting your progress.
Weve already discussed how certain nutrient deficiencies can predispose to developing autoimmune diseases.
This should give you an idea of the importance of nutrients and supplements in treating these conditions.
Now we need to discuss how certain nutrients can reduce inflammation and have even been shown to lower TPO antibody levels.
Supplements to reduce inflammation and autoimmunity:
Supplements to improve thyroid function:
In addition to using supplements, there are some medications that can be used to help reduce inflammation.
How To Heal Your Thyroid
Based on the results of the TPOAbs test, the doctor will recommend certain treatment measures if necessary.
However, there are many things you can do on your own in order to prevent or lower the levels of antibodies. These measures can help delay progression or aid management of autoimmune thyroid conditions. Below, you can see some useful suggestions:
- Modify your diet the first and most important thing you can do to lower levels of TPO antibodies is to modify your diet. Make sure to lower or avoid intake of heavily processed and refined foods, GMO foods, and foods laden with thickening agents, artificial sweeteners, thickening agents, food dyes, among others. Instead, try to include organic fruits and vegetables into your diet and other foods that are rich in nutrients and with amazing anti-inflammatory activity. You also need to consume fiber-rich foods which are beneficial for the digestive system i.e., your gut. Additionally, your diet also needs protein which assists in the repair of tissues in the body, participates in the transport of thyroid hormones throughout the body
What Does The Test Measure
Thyroid antibody testing detects and measures thyroid antibodies in the blood. Normally, antibodies attack foreign substances in the body, like bacteria, viruses, parasites and toxins.
In patients with autoimmune disorders, antibodies mistakenly target the bodys own tissues. These antibodies that attack the patients own body are also known as autoantibodies or antithyroid antibodies. Thyroid antibody testing may look for several types of thyroid antibodies:
- Thyroid peroxidase antibodies : Thyroid peroxidase is an enzyme that is crucial to the production of thyroid hormones. TPOAb may interfere with the action of this enzyme. Almost all patients with Hashimotos thyroiditis have high levels of TPOAb.
- Thyroglobulin antibodies : Thyroglobulin is a protein made by the thyroid gland. TgAb may be present when the thyroid has been damaged. Thyroglobulin antibodies are often measured in addition to thyroglobulin tests after a patient completes treatment for thyroid cancer.
- Thyrotropin receptor antibodies : TRAb are antibodies that bind to the receptors on thyroid cells normally activated by thyroid-stimulating hormone . In Graves disease, an antibody called thyroid stimulating immunoglobulin binds to the TSH receptor and mimics the action of TSH. This causes constant stimulation of the thyroid gland, prompting it to release too much thyroid hormone into the bloodstream. Stimulation by TSI can also cause abnormal growth of the thyroid gland.

What Your Tpo Antibodies Test Results Mean
The normal range for TPO Antibodies is less than 35 IU/mL.
A null to minimal TPO Antibody test means that your blood does not contain TPO antibodies. This normally insinuates that the causes of your thyroid symptoms are not due to an auto-immune disease. However, if these conditions are suspected then, a recurring test may be recommended.
When the levels are mildly elevated, this can be caused by many thyroid conditions like thyroid cancer, type-1 diabetes, rheumatoid arthritis, as well as auto-immune collagen vascular disease.
High levels of TPO Antibodies are usually caused by an autoimmune disease like the Hashimoto Thyroiditis, Graves Disease, pernicious anemia, lupus and rheumatoid arthritis. It has been reported that almost 3% of people who have a positive TPO test result do not show any symptom.
If levels are high in a pregnant woman, this may lead to higher risks of developing hypothyroidism or hyperthyroidism in the newborn baby.
What Do Tpo Antibodies Mean To You
TPO antibodies test informs the doctor whether symptoms you experience are associated with an autoimmune condition. But, if you already have some thyroid disease, its treatment is not really based on antibody levels.
After all, the treatment of thyroid condition is based on thyroid hormone levels and the severity of symptoms a patient experiences. Doctors order TPO antibodies tests to assess the potential cause of thyroid condition and identify the subclinical disease of the butterfly-shaped gland.
The doctor is less likely to treat the thyroid disease if a patient has high TPO antibodies without symptoms and with normal thyroid hormone levels. On the other hand, if a patient has mild symptoms or borderline abnormal thyroid hormone levels along with higher TPO antibodies, the doctor may recommend treatment. Again, the treatment will work to manage symptoms and normalize levels of thyroid hormones.

Thyroid Peroxidase Antibody Test: What Is It
Medically reviewed by Drugs.com. Last updated on Jul 16, 2022.
Thyroid peroxidase is an enzyme normally found in the thyroid gland. TPO plays an important role in the production of thyroid hormones. A TPO test detects antibodies against TPO in the blood. If you’ve been diagnosed with thyroid disease, your doctor may suggest a TPO antibody test and other thyroid tests to help find the cause.
The presence of TPO antibodies in your blood suggests that the cause of thyroid disease is an autoimmune disorder, such as Hashimoto’s disease or Graves’ disease. In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue. Antibodies that attack the thyroid gland cause swelling, rarely tenderness and reduced function of the thyroid.
Your doctor may also order a TPO antibody test if you are pregnant and have an autoimmune disease that involves the thyroid, such as Hashimoto’s disease or Graves’ disease.
Some people with TPO antibodies may not have thyroid disease. But the presence of TPO antibodies may increase the risk of future thyroid disorders.
Factors Linked To Thyroid Autoimmunity
Autoimmune thyroid diseases are usually accompanied by the presence of anti-thyroid peroxidase , anti-thyroglobulin , and anti-thyroid-stimulating hormone receptor antibodies. Antibodies against thyroid antigens such as carbonic anhydrase 2, megalin, T3 and T4, sodium iodide symporter , and pendrin have also been detected, although rarely .

Management Of Thyroid Peroxidase Antibody Euthyroid Women In Pregnancy: Comparison Of The American Thyroid Association And The Endocrine Society Guidelines
L. MehranAcademic Editor: Received
The presence of thyroid autoantibodies is relatively high in women of childbearing age. There is evidence that positive thyroperoxidase antibody even in euthyroid women may increase the risk of spontaneous and recurrent pregnancy loss and preterm delivery. However, the evidence is not enough to justify recommendation on the screening of pregnant women for thyroid autoantibodies or LT4 supplementation for reducing maternal or fetal complications. In this paper we reviewed the related evidence and compared the new guidelines of the American Thyroid Association and Endocrine Society with respect to the screening and management of positive thyroperoxidase antibody in euthyroid pregnant women. As there was no major contradiction or disagreement between the two guidelines, either one of two guidelines may be used by clinicians for the appropriate management of thyroid autoimmunity during pregnancy.
Given the potential association of thyroid autoimmunity and adverse pregnancy outcomes, it is of prime importance to screen pregnant women for thyroid autoimmunity and to manage thyroid antibody euthyroid women during pregnancy, when necessary.
Regarding the risk of postpartum thyroiditis in TPOAb women, none of the organizations recommend LT4, iodine, or selenium treatment to prevent PPT.
Thyroid Antibody Test Results
Antibody levels can be tested with a blood sample. The antibody test measures the amount of antibody per milliliter or liter of blood in international units.
Normal values are:
- TPO antibody: Less than 9 IU/mL
- Thyroid-stimulating immunoglobulin antibody : Less than 1.75 IU/L
- Anti-Tg antibody: Less than 4 IU/mL
Note that different laboratories may have different normal range values.
Why Might Your Doctor Test Your Thyroglobulin Antibodies Levels
Your doctor may check your TgAB levels if they suspect you have an underlying autoimmune condition causing thyroid dysfunction. A doctor may want to see the results of a TGAb test if they see specific clinical findings on your lab work and physical exam, including:
- Inflammation of the thyroid
- Abnormalities in other thyroid function tests like T4 and T3
While this may be a test occasionally used to detect autoimmune thyroiditis, it is more common to use this test to determine if treatment for thyroid cancer has been effective or not. Indeed, providers often use TgAB as a tumor marker because your body will only continue to produce TgABs if you still have thyroid tissue in your body. Thus, after thyroid cancer treatment, the goal is to have no TgABs in your lab work after your thyroid has been removed.
Conditions Associated With High Thyroid Peroxidase Antibodies
What does it mean if you have thyroid peroxidase antibodies floating around in your blood?
Well, it can mean several things:
- It may be a marker for the autoimmune disease known as Hashimotos thyroiditis.
- It may also be a marker for another autoimmune disease of the thyroid gland known as Graves disease .
- It may be a transient thing that may eventually go away on its own ).
The presence of thyroid peroxidase antibodies is never normal but it doesnt always guarantee a poor outcome.
For instance, as I mentioned above, some people see elevated antibodies during pregnancy which then fall after birth.
The significance of thyroid peroxidase in this exact setting is not well understood but it does give some hope that not every situation of elevated antibodies points to autoimmune disease.
Why would you want to check your thyroid peroxidase antibodies?
Your doctor can use this test in a number of useful ways:

What Do The Results Mean
Your results may show one of the following:
- Negative: no thyroid antibodies were found. This means your thyroid symptoms are probably not caused by an autoimmune disease.
- Positive: antibodies to TPO and/or Tg were found. This may mean you have Hashimoto disease. Most people with Hashimoto disease have high levels of one or both of these types of antibodies.
- Positive: antibodies to TPO and/or TSH receptor were found. This may mean you have Grave’s disease.
The more thyroid antibodies you have, the more likely it is that you have an autoimmune disorder of the thyroid. If you are diagnosed with Hashimoto disease or Grave’s disease, there are medicines you can take to manage your condition.

When Should I Get Testing For Thyroid Antibodies
It is not always necessary to test for thyroid antibodies to establish a diagnosis of an autoimmune disorder affecting the thyroid. However, doctors may find thyroid antibody testing helpful in the following situations:
- Subclinical hypothyroidism: In patients with a high TSH and a normal T4, testing for TPO antibodies may help predict whether the hypothyroidism will progress from being subclinical, in which it may not be causing significant or observable symptoms, to more severe and permanent dysfunction.
- Goiter: A goiter describes the abnormal enlargement of the thyroid gland. Some experts recommend testing for TPOAb in patients with a goiter, even if their thyroid hormone levels are normal.
- Hyperthyroidism, if the cause is not obvious: When patients have an overactive thyroid, sometimes it is clear from their physical examination and thyroid hormone tests that they have Graves disease. In less obvious cases, TRAb testing or imaging tests may be helpful in diagnosing or ruling out Graves disease.
- Monitoring after thyroid cancer treatment: Patients who are monitored with thyroglobulin testing after treatment may also have their TgAb levels tested as elevated TgAb can interfere with some thyroglobulin tests.
Although thyroglobulin antibodies may be elevated in both Hashimotos and Graves disease, it is not typically tested during diagnosis.

Autoantibodies As Potential Immunological Markers
TG and TPO antibodies provide readily available evidence for Graves disease although not specific, their presence in a patient with hyperthyroidism strongly suggests the diagnosis. These antibodies are present in 2030% of cases 57 years before diagnosis . TSAb are not generally measured because present bioassays are laborious. TBII estimation is a commercially available surrogate and is useful in confirming the diagnosis of Graves disease in the absence of clinical evidence such as ophthalmopathy. TSAb or TBII levels have been investigated as predictive markers for the success of antithyroid drug treatment in Graves disease. Although patients with the highest levels tend to relapse the most, the results are insufficiently accurate for clinical use . The most important indication for TSAb assay in Graves disease is in women with known Graves disease during pregnancy to predict the risk of neonatal thyrotoxicosis .

What Is Thyroid Peroxidase Antibody
An antibody is a protective protein produced by the immune system against an antigen, a foreign substance. Antibodies help remove antigens from the body by binding to them. When antibodies attack the body cells, they produce an autoimmune response. Thyroid peroxidase antibodies prevent thyroid peroxidase from catalysing the production of thyroid hormones.

Certain Conditions Can Make Your Thyroglobulin Antibody High
Even though antithyroglobulin antibodies are not the best predictor of thyroid disorders, they should not necessarily be ignored. Unlike TPO antibodies, thyroglobulin antibodies are not able to stimulate an immune response in the thyroid, but they may be useful in diagnosing certain thyroid conditions .
Anti-TG antibody levels may show importance in the following:
- Patients diagnosed with thyroid carcinoma who have elevated TG antibodies may be at a higher risk of the cancer spreading to lymph nodes or surrounding organs. Elevated levels may also indicate a high risk of thyroid cancer recurrence after treatment [4
- Trusted SourcePubMedGo to source].
One study found that after successfully treating thyroid disease, thyroglobulin levels dropped back down into normal reference ranges . It is important to point out that this study tested the actual levels of thyroglobulin protein, not the TG-antibody levels.
However, this finding is consistent with another study that found elevated anti-TG antibodies to correlate with the severity of hypothyroid symptoms, including fragile hair, swelling of the face and eyes, and vocal hoarseness [3
Thyroglobulin autoantibodies may not be the best indicator of thyroid disease, but likely will continue to be useful in the screening and monitoring of select conditions.
Other Thyroid Antibodies Like Tpo May Be More Useful
Thyroid peroxidase antibody levels are a much stronger indicator of an increased risk for thyroid disease. TPO antibodies are 90% sensitive in detecting thyroiditis, and are effective in monitoring the progression and severity of thyroid conditions [2
The normal reference range for TPO antibodies is less than 35 IU/mL. But a 2016 study published in the Journal of Hormone and Metabolic Research [9
- Those who had TPO antibodies below 500 IU/mL had a low risk of future progression to hypothyroidism.
- Those who were above 500 IU/mL still only had a moderate risk.
The Tehran Thyroid Study, which followed the course of thyroid disease in a large cohort of people over nine years, showed similar results: those with elevated TPO antibodies only had a 9-19% chance of becoming hypothyroid after 6 years of follow up .
If we consider this, elevated thyroid antibodies are not as consequential as many thyroid experts would suggest.
Ive commonly seen people with Hashimotos disease or elevated thyroid antibodies become hyper-focused on reducing their antibody test results to the normal reference range, and becoming unnecessarily stressed. The research suggests this isnt necessary.
